The notice does not identify the attacker, explain the initial access method, state how long access lasted, or name the systems that were encrypted.

The letter also outlined protective options including credit freezes, fraud alerts, and reporting suspicious activity.\u003C\u002Fp>\n\u003Ch2>What Should Affected People Do?\u003C\u002Fh2>\n\u003Cp>Notice recipients should rely on the scope stated in their individual letters and be cautious with unexpected messages involving payroll, taxes, or employment history. Credit reports and financial accounts may be monitored for unfamiliar activity, and links claiming to be from the company or monitoring provider should be verified through the msusi.com domain or the contact information in the official letter before use.\u003C\u002Fp>","","Mario Susi & Son Data Breach: At Least 175 Affected","Payroll information for at least 175 people may have been affected in the Mario Susi & Son ransomware attack.
